Stack trace:
java.lang.RuntimeException: None of the basic classes could be loaded! Check your Soot class path! at soot.Scene.loadBasicClasses(Scene.java:1755) at soot.Scene.loadNecessaryClasses(Scene.java:1845) at soot.Main.run(Main.java:241) at soot.Main.main(Main.java:141) at MySootTest.main(MySootTest.java:54)
Okay, the error is telling us that soot did not find the rt.jar .
In your command line options can you please omit the cmd-parameter cp and just use the cmd-paramter -process-dir.
Given your command line, soot uses the classpath -cp lib\soot-4.2.1-jar-with-dependencies.jar;. and tries to find rt.jar in these directories. Obviously, soot is unable to locate the rt.jar, and thus fails to load basic classes, e.g., String, Object, etc.
Remediated the soot classpath runtime exception by setting the below options to execute the soot and run callgraph.
Options.v().set_verbose(false); Options.v().set_keep_line_number(true); Options.v().set_src_prec(Options.src_prec_class); //Options.v().set_soot_classpath(classpath); Options.v().set_prepend_classpath(true); Options.v().set_soot_classpath(classpath);
But facing issue with callgraph as Soot is unable to run with main method in spring mvc code . kindly assist how to do a callgraph in spring-mvc
Super, that the RuntimeException is fixed! Can you give more details concerning the issue? Does not soot find the main method?

Callgraph is not working and soot is throwing above exception
@pikuit In the options you set to resolve the runtime exception, what did you set as classpath?
